The MS-704 is a four-channel main station that contains a no-fail system power
supply. The RM-704 is a four-channel remote station intended to be powered
from the intercom line.
The following is a list of features found in the MS-704 and RM-704 intercom
stations:
• MICROPROCESSOR CONTROL: Most aspects of station operation are
under microprocessor control.
• REMOVABLE ACCESS PANEL: A removable access panel allows access to
most controls and option DIP switches.
• INDIVIDUAL CHANNEL CONTROLS: Each channel has individual
talk, listen, and call pushbuttons for each channel.
• MOMENTARY/LATCHING TALK BUTTONS: The talk buttons have a
momentary and latching action depending on how the button is used. The
latching function can be defeated with DIP switches.
• INDIVIDUAL CHANNEL ADJUSTMENTS: Each channel has
individual listen level controls, channel null adjustments, and program feed
level controls.
• MULTIPLE PROGRAM INPUTS: Multiple program inputs are provided
for local station monitoring and program feed to intercom lines for local
talent cuing (IFB).
• INTERNAL IFB (IFB - Interrupt Foldback of program feeds): Program
can be fed to each channel and interrupted (IFB) when a talk function is
active or when a call signal is received on that channel. An internal jumper
determines whether the IFB function is talk- or call-signal activated.
• LINK FUNCTION (MS-704): The MS-704 has a link function that places
all channels into a common party-line at the push of a single button.
• ALL-TALK: An all-talk button allows instant access to all channels.
• ANNOUNCE FUNCTION: An announce button allows external paging.
A set of relay contacts is provided to control an external system.
• PROGRAM FEED OVER STAGE ANNOUNCE: An internal jumper
allows the main program feed to be fed to the stage announce output. The
program is automatically interrupted when the announce button is pressed.
• MIC ON/OFF SWITCH: A separate mic on/off push-button allows
turning the microphone off without upsetting the setting of talk switches.
• REMOTE MIC KILL SWITCH (MS-704): Front-panel switch allows you
to turn off all latched talks on remote stations and beltpacks.
• EXTERNAL MIC ON/OFF INPUT: An external logic input allows the
mic on/off function to be switched remotely.
• EXTERNAL IFB and HOT MIC OUTPUT: A rear panel jack provides
direct connection to Clear-Com’s external IFB system such that the station’s
microphone can be used in the external IFB system. A buffered unswitched
output of the selected microphone is also available.
